I'd rather be attacked my a cat. When I was young, a dog viciously attempted to attack me. It's first attempt was lunging at my face trying to rip it off, but I dodged. If the owners weren't right there, I don't know what would have happened. If a cat attacks, it generally will not try to kill you. If a dog deems you a threat in their territory, they won't stop unless their owner constrains them.
